Description

Technical Field

[0001] This utility model relates to the technical field of fabric fastening devices, specifically to a fastening device for workwear fabric. Background Technology

[0002] A button-attaching device is a piece of equipment used to automatically or semi-automatically attach buttons to fabric. It is widely used in industries such as textile and garment processing and bag manufacturing. For example, patent document CN216998790U discloses a button-attaching device for workwear fabric. This device places the fabric on a base plate above the button-attaching device, and then the button slides down from top to bottom through a guide channel into the inside of a retaining ring. Then, the fitting part on the micro motor pushes the button to the corner for fixation, thereby enabling button-attaching. This allows for precise alignment of the button and the needle, making it less likely for the sewing needle to break.

[0003] However, the spacing between the needle holes inside the existing button sewing device is fixed. When the specifications of the buttons to be sewn are different, the position of the needle hole cannot match the eyelet inside the button, making it impossible for the needle to pass through the needle hole and eyelet stably to complete the fast sewing of the button to the work clothes fabric.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a button-fastening device for work clothes fabric.

[0025] This utility model provides, for example Figure 1-4 The workwear fabric fastening device shown includes a base plate 1 and an inclined slide 2 fixed to the side of the base plate 1. A retaining ring 3 is placed on the top of the base plate 1. Multiple mounting bolts 4 are threaded between the retaining ring 3 and the base plate 1. A support frame 5 is fixed to the outer wall of the base plate 1. An electric push rod 6 is fixed to the outer wall of the support frame 5. A push plate 7 is fixed to the output shaft of the electric push rod 6. The push plate 7 is located inside the retaining ring 3. An embedding groove matching the output shaft of the electric push rod 6 is opened on the top of the retaining ring 3. Multiple axially uniform strip holes 8 are opened inside the base plate 1. A needle tube 9 slides through the inner wall of the strip hole 8. An elastic telescopic rod 13 is fixed between the needle tube 9 and the inner wall of the strip hole 8. The elastic telescopic rod 13 consists of a telescopic rod and a spring sleeved on the outside of the telescopic rod.

[0026] In order to enable the rapid adjustment of the positions of multiple needle tubes 9, such as Figure 2-4 As shown, an adjustment and positioning mechanism for adjusting the position of the needle tubes 9 is provided between the multiple needle tubes 9. The adjustment and positioning mechanism includes multiple push blocks 10 that are evenly distributed axially. A vertical rod 11 is rotatably provided at the bottom of the base plate 1. A rotating block 12 is fixedly sleeved on the rod wall of the vertical rod 11. The multiple push blocks 10 are fixedly connected to the rotating block 12 and contact and cooperate with the outer wall of the needle tube 9. Both sides of the outer wall of the multiple push blocks 10 are set with slopes.

[0027] A mounting plate 14 is fixedly installed at the bottom of the base plate 1. A motor 15 is fixedly installed on the back side of the mounting plate 14. The output shaft of the motor 15 passes through the mounting plate 14 and is fixedly installed with a worm gear 16. A worm wheel 17 is fixedly sleeved on the wall of the vertical rod 11. The worm wheel 17 and the worm gear 16 are configured to cooperate.

[0028] Working principle: Before sewing buttons, the positions of multiple needle tubes 9 are adjusted according to the button specifications and internal hole positions. First, the motor 15 is started, and its output shaft drives the worm wheel 17 through the worm gear 16 to rotate the vertical rod 11 and the rotating block 12. The push block 10 (with an inclined outer wall) on the rotating block 12 pushes the needle tubes 9 to slide in the strip hole 8, compressing or stretching the elastic telescopic rod 13 (composed of a telescopic rod and a spring) to adjust the spacing of the needle tubes 9 to match the button hole. After the motor stops, the spring force maintains the positioning. Then, the button is put in from the inclined slide 2 and slides into the retaining ring 3. The electric push rod 6 drives the push plate 7 to push the button to the edge of the retaining ring 3 for fixation. Then, the fabric is placed above the retaining ring 3, and the needle in the needle tube 9 passes through the fabric and the button hole to complete the sewing. After the operation is completed, the electric push rod 6 retracts, and unused buttons can be fed again through the inclined slide 2 for repeated operation.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
